FAQ — Image Resizer Free Online Tool

What fit mode should I use?

Cover = crop to fill (may cut off edges). Contain = fit inside (may add letterbox). Stretch = force exact dimensions (may distort).

What is the best output format?

WebP = smallest file size with good quality. AVIF = even smaller but less browser support. JPG = max compatibility. PNG = only if you need transparency.

Is my image data private?

Images are processed server-side (using Sharp). They are not stored permanently. Uploaded images are deleted after processing.
